4 Claims. .(CL182F25) 7 -matic device of this character which isstructurally sound, and is capable of being easily taken apart andassembled for repair and replacement purposes.

Other objects and advantages of my invention will be apparent from areading of the following description of the drawings, wherein forpurposes of illustration Ihave showna preferred embodiment of myinvention.

In the drawings:

Figure 1 is'a vertical transverse sectional View through the embodiment.

Figure 2 is a horizontal sectional view through Figure 1 takenapproximately on the line 2-2 and-looking downwardly.

Figure-3 is a top plan view-of the'strainer.

Figure 4 is a side elevational view of the float.

Referring in detail to the drawings, the numeral 5 generally designatesa vertical cylindrical sewer pipe of cast iron which acts as the casing.The casing is provided at its lower end with a portion 6 which is oflarger interior and exterior diameter than the upper part of the casing,and the portion 6 is provided with interior screwthreads I which arearranged for mounting the casing and connecting it with the sewer pipeelbow (not shown).

Within the main portion 1 of the casing is a radially inwardlyprojecting flange 8 which provides a concentric circular opening 9.Below the flange 8 is a sleeve 9' which snugly fits within the casingportion 1'. The lower end of the sleeve 9' is substantially on a levelwith the lower end of the interior of the casing portion 1', while theupper end of the sleeve 9 fits against the lower side of the interiorflange 8. At the upper end of the sleeve 9' is an annular top portionII] which has on its inward edge a thickened vertical flange I! forminga collar which fits within the opening 9 defined by the flange 8 andreaches a point on a level with the top of the flange 8. A cross memberwhich is vertically elongated is arranged across the opening l3 in thecollar H for slidably supporting the float structure to be described.

Resting its lower end upon the top of the collar II is a strainer M.This comprises a relaa suitable number-of holes l6. As isobvious-inFigure l, the cylindrical'portion E5 of the strainer is considerablyradially spaced from the interior walls of the upper part of the casingportion l, whereby a water receiving chamber I1 is defined. Theupper'end of'the cylindrical portion of the strainer is provided with aplate 18 which is considerably larger in diameter than the upper end ofthe cylindrical portion 55 of the strainer and has its outer edgesseated in an annular groove 19 which is radially outwardly formed at theupper end of the casing portion -i. The plate i8 is provided withholes2!] which are located in a position to empty sewage into the sewagereceiving chamber ll, the central portion of the plate 23 over thecylindrical portion I5 of the strainer being imperforate, whereby thesewage is made to pass through and be strained by the-cylindricalportion l5 before it flows through the opening l3 defined by the collarI! into the lower portion of the casing.

The outside of the collar H is milled toprovide an adequate engagementwith the opening 9 defined by the flange '8 so thatthe sleeve 9 isproperly supported in position.

Slipped into the sleeve 9 and engaging the side walls thereof as well asthe lower side of the top Wall in is a compressible washer which hasopening at its lower side hemispherical recess 22. A cylindrical passage23 is provided through the top of the washer and communicates with theopening I 3 defined by the collar I l on the sleeve 9. As shown inFigure 1 the lower end of the washer is approximately on a level withthe lower end of the sleeve 9.

For cooperation with the compressible washer 2i and for engaging itshemispherical recess 22 so as to close the vertical passage 23, is ahemispherical hollow float 24 which has projecting axially from itsupper side a bifurcated standard 25 whose legs are arranged on oppositesides of the cross member l2 carried by the collar H. A removable pin 26traverses the upper ends of the legs of the standard 25 and holdsbetween the 'tively small diameter vertical: cylindrical hollow portionl5 which is provided in its sides with legs at this point a bearingmember 2'5 which is arranged above the cross member I2 and to restthereon when the float is in the lower position, as shown in Figure 1.Whenever sewage backs up through the sewer pipe elbow-into the lower endof the casing 5, the float 24 will be carried upwardly by the sewageuntil it reaches a position in engagement with the washer 2| in themanner described, in which position it will cooperate Although I haveshown and described herein a preferred embodiment of my invention, it isto be definitely understood that I do not desire to limit theapplication of the invention thereto,

and any change or changes may be made in material and structure andarrangement of parts, within the spirit of the invention and the scopeof the subjoined claims.

What is claimed is:

1. In a device of the character described, a vertical casing, a strainerin the upper end of the casing, radially inwardly projecting meanswithin the casing defining a passage, an annulas within the casing atone side of said radially inwardly projecting means and having the lowerside of its opening formed with a substantially hemispherical concavity,and a float having a substantially hemispherical upper portion, saidfloat being arranged to riseand engage its hemispherical upper portionwith said concavityfor closing said passage.

2. In a device of the type described, a vertical casing having aradially inwardly projecting shoulder dividing the interior of thecasing into upper and lower compartments and defining a passagetherebetween, a vertical tubular member connected to said shoulder so asto be supported above said shoulder, the walls of said tubular memberbeing perforated to strain 'fluid passing from openings in thetop of thecasing to said passage, the lower side of said shoulder adjacent saidpassage having a portion hernispherically concaved to provide a valveseat of unusually large area, and a float valve having a substantiallyhemispherical upper portion arranged to conformably engage with a majorportion of said valve seat to close said passage.

3. In a device of the type described, a vertical casing having aradially inwardly projecting shoulder dividing the interior of thecasing into upper and lower compartments and defining a passagetherebetween, a vertical tubular member connected to said shoulder so asto be supported above said shoulder, the walls of said tubular memberbeing perforated to strain fluid passing from openings in the top of thecasing to said passage, the lower side ofv said shoulder adjacent saidpassage having a portion hemispherically concaved to provide a valveseat of unusually large area, and a ficat valve having a substantiallyhemispherical upper portion arranged to conformably engage with a majorportion of said valve seat to close said passage, said hemisphericallyconoaved portion being formed of compressible material whereby closeengagement of said float valve with a major portion of the concavitythereof is assured.

4. In a device of the type described, a'vertical casing having aradially inwardly projecting shoulder dividing the interior of thecasing into upper and lower compartments and defining a passagetherebetween, a vertical tubular member conformably engage with a majorportion of said valve seat to close said passage, across membersupported in said passage adjacent said shoulder, a pair of arms risingfrom said float valve and slidably engaging opposite sides of said crossmember, and a member joining said arms and engageable with the upperside of said cross member while said valve is in the extreme depressedposition for supporting said valve.
